Interbus commissioned Duvolle Laboratories to design them an upgraded shuttlecraft in YC 106. The result was this vessel, which combines compact size with a surprisingly large cargo hold - ideal for the multipurpose transportation that Interbus specializes in.
The ship remained a closely-guarded Interbus asset for many years, but in YC111 it was made available to select capsuleer pilots as part of an outreach programme intended to raise awareness of the Interbus brand among the growing capsuleer population. It remains, however, a very rare sight among the spacelanes and is considered by many to be a valuable collector's item.
The Interbus shuttle is a special release version of the standard Gallente shuttle. Originally released as a bonus to those who bought the boxed version of EVE Online, it has since been discontinued and is now considered a premier collectors item, and almost never seen outside of a station. It does have an advantage over the standard shuttle by having twice the cargo capacity, but due to the rarity it is better to use a frigate or larger ship if you need the extra capacity.
